Description
What Is a Slitting Saw?
A slitting saw, also known as a slitting saw blade, slotting saw, or metal slitting cutter, is a thin circular cutting tool used on milling machines and CNC machining centers to produce narrow slots, grooves, keyways, parting cuts, and precision cut-off operations.
Compared with conventional end mills, slitting saws provide several advantages:
- Higher cutting efficiency
- Better dimensional accuracy
- Improved chip evacuation
- Lower cutting forces
- Reduced material waste
- Better performance in deep slotting and thin-wall machining
Typical applications include:
- Slot milling
- Keyway cutting
- Parting and cut-off operations
- Trimming operations
- Deep groove machining
- Thin-wall component machining
- Precision metal cutting
Selecting the proper saw material, tooth form, coating, and precision grade is essential for maximizing tool life, machining productivity, and finished part quality.
